Add functions to an Enum

Question

Is it possible to add functions to an Enum type in TypeScript?

for example:

enum Mode {
    landscape,
    portrait,

    // the dream...
    toStri         


        

Answer 1

An addition to Fenton's solution. If you want to use this enumerator in another class, you need to export both the enum and the namespace. It would look like this:

export enum Mode {
    landscape,
    portrait
}

export namespace Mode {
    export function toString(mode: Mode): string {
        return Mode[mode];
    }
}

Then you just import the mode.enum.ts file in your class and use it.
